A dial-a-ride problem for public transport using electric vehicles

Coauthor: Janny M. Y. Leung


With concern about environmental quality growing in the world, sustainable transportation systems, such as on-demand public transit and the usage of electric vehicles (EV), are developing in many cities. An on-demand public transport system works similar to a taxi service, but combines the servicing of customers with similar routes in the same vehicle so as to reduce operational cost and impact to the environment. The usage of EV can further reduce pollution levels. We combine these two eco-friendly concepts to study a variant of the Dial-a-Ride problem (DARPEV), which aims to minimize the total distance travelled subject to meeting all customers' requests, and constraints on vehicle capacity, pickup/ delivery time-window, customer ride-time and battery-charging restrictions. Using EV limits the travelling time between battery recharges. The restricted charging locations and the requirement that charging must be done with no customers in-service complicate the problem, as extra variables and constraints are added. Computational results and further research directions are discussed.
